Re: hull extension in progress with picks
ok....ill try this again......
during the time i was making the benches.....i was also building the swim platform. the whole idea was to be able to gellcoat the benches and the platform at the same time.
normally.....when a fiberglass part is made.....its a three step process.
first a sculpture is made, uasually made of wood this sculpture is exactally what the part looks like......this is called a plug. after the plug is carved.....it is painted and waxed
the plug is then fiberglassed using tooling resin. the fiberglassed area is uasually reinforced from the outside so the shell of fiberglass has some rigidity to it.
after the giberglassed plug cures.....i8t glass is removed form the plug......the galssed peice is called the mold......the mold is then faired and waxed as smooth as possible.
after waxing......the mold is gellcoated, then after its cured its fiberglassed using a chopper gun or traditional methods of lay ups.
well when ol oops did his.....he wanted to skip a few steps...!
would have worked too if murphy hadent shown up!
one of the things i wanted to do was work with foam.......i will be using it in later stages of this project, so i wanted to get used to it!
i chose rigid insulating foam as the medium instread of wood for the mold.,
no klu and i hunted construction sites in the area for these peices.
the next was to prep the surface of the mold.....i used contact cement to apply the arbourite to the osb.
the arbourite chosen was not a smooth surface but a slightly pebbeled one that would give some kind of non slip surface.
using the contact cement it was applied to the board.
the most crutial thing in building a swim grid is to make surte that the angle of the platform is level to the water line.....that means you must come off the transom at the correct angle.........i eyebelled it!
the foam is to make up the side walls of the form.
